Wires, cables & harnesses
Capabilities & Specifications
SureSource manufactures the full range of wire, cable, and harness products — from bulk wire and cable through pre-wired connectors and simple two-conductor assemblies to complex multi-conductor and power harnesses for automotive and industrial use. Capabilities include HDMI, VGA, and audio cable assembly, high power EV harnesses, custom charging cables, and application-specific harnesses built to your pinout and connector spec.
In-house DFM review confirms conductor gauge, insulation rating, and connector compatibility before production, which matters most on multi-conductor and automotive harnesses where a wiring error is expensive to catch late. We manage certification and compliance documentation (UL, CE, FDA, FCC, RoHS, REACH) and support continuity and pull-strength testing as part of QC.
MOQs vary by complexity — bulk wire and simple two-conductor assemblies can run smaller batches, while custom multi-conductor harnesses with specific connectors typically need higher volumes to justify tooling for connector crimping and testing fixtures.

Frequently Asked Questions
What types of wire, cable, and harness products can SureSource manufacture?
Bulk wire and cable, pre-wired connectors, HDMI/VGA/audio/high power cable assemblies, and custom multi-conductor harnesses including automotive applications.
What's the difference between working with a turnkey harness manufacturer and sourcing wire and connectors separately?
A turnkey partner manages wire sourcing, connector crimping, assembly, and testing under one contract. Sourcing components separately means you’re responsible for compatibility and QC across multiple suppliers yourself.
Can you build custom automotive or industrial wire harnesses to spec?
What's a typical MOQ for custom cable harness manufacturing?
How do you handle quality control for wire and cable assemblies?
Continuity, environmental, and pull-strength testing plus outgoing QC, with certification documentation (UL, CE, FDA, RoHS, REACH) provided before shipment.
